Soil bulk density determination method
WebWe developed a rapid method utilizing a low-cost hand sampler (< $125) for determination of soil bulk density over several intervals to a depth of 300 mm. The method appears … WebThe bulk density (BD, Mg m −3) was determined with the thermogravimetric method, on the basis of the ratio of the mass of soil dried at 105 °C to the initial volume of the soil (100 cm 3). In the following development of PTFs, their recalibration and validation, the mean BD value was applied.
